First look at Hades II

Just this morning I was wondering if I should play Hades II in Early Access when it becomes available, and I wasn't sure if I wouldn't rather wait for when 1.0 comes out.
Aaand then Supergiant streamed Amir Rao and Greg Kasavin playing the technical test, i.e. the first phase, and I immediately forgot all arguments and watched it immediately. Given how weak I am at resisting spoilers I think I will play Early Access so I'm not yet fully spoiled for everything when I play. And it looks like so much fun!
